✓ Figure No. 5 illustrates levels at three wells owned by the City of Banning in the
Southeast portion of the basin. While water level at the Old Well No. 15 (Chevron
Well) has been fairly flat over the last two years, a somewhat significant and steady
decline, close to 23 feet, was recorded at Banning M-8 between the summer of
2015 and the winter of 2017. The probe at Banning M-8 was removed in late
January 2018 and the pump was recently removed. We are currently discussing
with operations staff the possibility of reinstalling a water level probe at this well.
Water level at Banning M-9 has fluctuated in a 13-foot range, between 2,134 ft and
2,147 since monitoring began in the summer of 2015. Currently, water elevation
is at 2,138 ft. Water level over the last two months are not depicted in the figure
due to problems with the communications cable.

✓ Figure No. 6 illustrate recorded water level at BCVWD No. 2 and the new
monitoring well BCVWD No. 25. Over the last two years, the level at BCVWD No.
2 has increased by over 26 feet and is currently at the highest elevation recorded
since monitoring began. Water level at BCVWD No. 25 is in sync with BCVWD
No. 2 despite of pumping close to 18 hours a day and it is also at the highest level
recorded. Over the last six months, the water level at these two wells has
increased by 10 ft at each well.

New Monitoring Wells

Since the last reporting period, two new wells have been equipped with monitoring
equipment. These two wells are located in the western portion of the basin where we
information was lacking. BCVWD No. 29, similar to BCVWD No. 25, is a production well
that is normally operated 18 hours a day during the summer to take advantage of Time
of Use (TOU) energy schedules. Water levels at this well will be recorded hourly; the
highest daily level will be used as a representation of static water conditions. The second
well is Tukwet Golf Course Well B, which is a non-production well at this time and will be
used to monitor water levels in the southern portion of the basin. The location of these
wells is depicted in Figure 1 below.

New Equipment Installation

✓ A new communications cable (500 ft long) was installed at BCVWD No. 2

✓ A new communications cable (200 ft long) was installed at Oak Valley Well No. 5

Troubleshooting Issues

The following malfunctioning issues were encountered during our January 22, 2019 field
visit:

✓ Banning M-9 – Communications cable did not allow us to upload water level
information from the probe; however, the probe continues to record levels on an
hourly basis. A new communications cable may be necessary at this well if
communications cannot be established.
